NGC 3675 is a spiral galaxy located in the constellation Ursa Major. It is located at a distance of about 50 million light years from Earth, which, given its apparent dimensions, means that NGC 3675 is about 100,000 light years across. It was discovered by German-British astronomer William Herschel on 14 January 1788.[2] NGC 3675 belongs to the Ursa Major Cluster, part of the Virgo Supercluster.[3]

It hosts a low-ionization nuclear emission-line region (LINER).[4] In the nucleus there is a supermassive black hole with an estimated mass of 10-39 million M☉, based on the intrinsic velocity dispersion as measured by the Hubble Space Telescope.[5] Although the galaxy was reported to have a strong bar visible in infrared images, there has been no indication of a bar in further observations.[6] Its spiral disk is of type III and there is a dust structure which is more prominent to the east.[7] The galaxy features two ring structures, with diameter 1.62 and 2.42 arcminutes.[8] The spiral arms are tightly wound and form an inner pseudoring and they continue for one revolution outside the ring. The outer arms are very patchy and filamentary.[9]

One supernova has been observed in NGC 3675: SN 1984R (type unknown, mag. 13) was discovered by Kaoru Ikeya on 2 December 1984.[10][11]
